I'm not sure which is better, I've heard good and bad about all of them!
Which is better Bosch Platinum+4 Spark Plugs or DENSO Iridium Spark Plug?
And Ford Racing 9mm Plug Wires or Bosch Premium Spark Plug Wire Set?
doesnt iridium tend to flake off? or is that a problem with all coated plugs including platinum. Is there a specific part number for the autolite plugs, im going to change mine soon.. and if those are the best im sure not going to pay for Denso's
